Is the object-server running on the node and is it using port 6000 and does it have recon in the pipeline e.g.
grep pipeline /etc/swift/object-server.conf [pipeline:main] pipeline = recon name_check object-serve Gerry From: pragya jain [mailto:[email protected]] Sent: 11 March 2014 06:17 To: Drudy, Gerry; Steve Mayer Cc: [email protected] Subject: Re: [Openstack] swift recon query Thanks Drudy Gerry for answering my queries. But when I use curl command for recon, I get the following results: root@swift-VirtualBox:~# curl -i http://127.0.0.1:6000/recon/mounted curl: (7) couldn't connect to host I don't understand where is the problem. Please help. Thanks Pragya Jain On Friday, 7 March 2014 3:51 PM, "Drudy, Gerry" <[email protected]> wrote: Comments inline. From: pragya jain [mailto:[email protected]] Sent: 07 March 2014 05:33 To: Steve Mayer; Drudy, Gerry Cc: [email protected] Subject: Re: [Openstack] swift recon query Hello Steve, My questions about swift recon are: Q1: what should be the curl command for recon? For example, to get a list of mounted devices on an object server: curl -i http://<an-object-server-ip>:6000/recon/mounted Q2. what arguments should I use with 'swift-recon' command to get the status about (i) /proc/meminfo, I’m not sure you can get meminfo using the swift-recon command. But you can use curl to get meminfo from a node, the following is a request to an object server: curl -i http://<an-object-server-ip>:6000/recon/mem (ii) currently mounted file systems Use ‘swift-recon –d’ (iii) list of devices Same as ii. Q3. When I run swift-recon command, It respond in terms of low: <> high: <> avg: <> total: <> failed: <> no_result: <> For example, root@swift-VirtualBox:~# swift-recon account --auditor =============================================================================== --> Starting reconnaissance on 4 hosts =============================================================================== [2014-02-12 15:05:20] Checking auditor stats [account_auditor_pass_completed] low: 0, high: 0, avg: 0.0, total: 0, Failed: 0.0%, no_result: 0, reported: 1 [account_audits_passed] - No hosts returned valid data. [account_audits_failed] - No hosts returned valid data. [account_audits_since] - No hosts returned valid data. What is the meaning of following terms: low, high, avg, total, failed, no_result, and reported ? Typically the ‘low’ would indicate the value from a node with the lowest value. For example if you are looking at async pendings, each node will have a different async pending queue length. The low value indicates queue length for the node with the smallest queue length, while the high indicates the longest async pending queue length and avg is the average queue length for all nodes. The total is the total number of async pending across all nodes. I think reported typically means the number of nodes it has got a result from? I can’t give you a clear definition of failed and no_result!

Try running with the '-d' or '-l' arguments to see some actual statistics. -- Steve Mayer [email protected]<mailto:[email protected]> On 6 Mar 2014, at 2:31, Drudy, Gerry wrote: > Add the verbose option to swift-recon: > > swift-recon -av > > It will list all the object servers in the ring.
